The method further can include retrieving one or more entity rules corresponding to entity data of the user request. The method also can include overwriting entity information of the entity data corresponding to the one or more entity rules. Additionally, the method can include outputting the output. Furthermore, the method can include transmitting, to the user device, a response to the user. Other embodiments are disclosed.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 16/779,280, filed Jan. 31, 2020, to be issued as U.S. Pat. No. 11,488,594. U.S. patent application Ser. No. 16/779,280 is incorporated herein by reference in its entirety.

TECHNICAL FIELD

This disclosure relates generally to automatically rectifying in real-time anomalies in natural language processing systems.

BACKGROUND

Natural language processing systems are commonly used in applications such as customer service, chatbots, machine translation, search engines, online or telephonic ordering, or virtual assistants, etc. Many systems with natural language processing or understanding abilities rely on machine learning modules, subsystems, or systems to expand their lexicon and improve accuracy. However, unlike rule-based processing, machine learning takes time. Although anomalies caused by new information, such as new terms or new categories, can be rectified eventually by updating and/or retraining the machine learning model, before the model can be updated or retrained, users of the natural language processing systems can encounter incorrect and inconsistent results, which can damage the user experience. Therefore, a mechanism for rectifying anomalies in real-time that is easy to implement yet effective is desired.

For simplicity and clarity of illustration, the drawing figures illustrate the general manner of construction, and descriptions and details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the present disclosure. Additionally, elements in the drawing figures are not necessarily drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help improve understanding of embodiments of the present disclosure. The same reference numerals in different figures denote the same elements.

The terms “first,” “second,” “third,” “fourth,” and the like in the description and in the claims, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms “include,” and “have,” and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, device, or apparatus that comprises a list of elements is not necessarily limited to those elements, but may include other elements not expressly listed or inherent to such process, method, system, article, device, or apparatus.

The terms “left,” “right,” “front,” “back,” “top,” “bottom,” “over,” “under,” and the like in the description and in the claims, if any, are used for descriptive purposes and not necessarily for describing permanent relative positions. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the apparatus, methods, and/or articles of manufacture described herein are, for example, capable of operation in other orientations than those illustrated or otherwise described herein.

The terms “couple,” “coupled,” “couples,” “coupling,” and the like should be broadly understood and refer to connecting two or more elements mechanically and/or otherwise. Two or more electrical elements may be electrically coupled together, but not be mechanically or otherwise coupled together. Coupling may be for any length of time, e.g., permanent or semi-permanent or only for an instant. “Electrical coupling” and the like should be broadly understood and include electrical coupling of all types. The absence of the word “removably,” “removable,” and the like near the word “coupled,” and the like does not mean that the coupling, etc. in question is or is not removable.

As defined herein, two or more elements are “integral” if they are comprised of the same piece of material. As defined herein, two or more elements are “non-integral” if each is comprised of a different piece of material.

As defined herein, “approximately” can, in some embodiments, mean within plus or minus ten percent of the stated value. In other embodiments, “approximately” can mean within plus or minus five percent of the stated value. In further embodiments, “approximately” can mean within plus or minus three percent of the stated value. In yet other embodiments, “approximately” can mean within plus or minus one percent of the stated value.

As defined herein, “real-time” can, in some embodiments, be defined with respect to operations carried out as soon as practically possible upon occurrence of a triggering event. A triggering event can include receipt of data necessary to execute a task or to otherwise process information. Because of delays inherent in transmission and/or in computing speeds, the term “real-time” encompasses operations that occur in “near” real-time or somewhat delayed from a triggering event. In a number of embodiments, “real-time” can mean real-time less a time delay for processing (e.g., determining) and/or transmitting data. The particular time delay can vary depending on the type and/or amount of the data, the processing speeds of the hardware, the transmission capability of the communication hardware, the transmission distance, etc. However, in many embodiments, the time delay can be less than approximately one second, five seconds, ten seconds, thirty seconds, or a minute.

In many embodiments, system 310 can be modules of computing instructions (e.g., software modules) stored at non-transitory computer readable media that operate on one or more processors. In other embodiments, system 310 can be implemented in hardware. Additional details regarding system 310, NLU preprocessing subsystem 311, ASR subsystem 312, ML subsystem 313, request processing subsystem 314, entity rule subsystem 315, admin module 316, and/or user device 320 are described herein.

In some embodiments, system 310 can be in data communication, through a computer network, a telephone network, or the Internet (e.g., network 340), with user device 320. In some embodiments, user device 320 can be used by users, such as user 330. In a number of embodiments, system 310 can host a website, or provide a server that interfaces with an application (e.g., a mobile application or a web browser), on user device 320, which can allow user 330 to browse and/or search for items (e.g., products), to add items to an electronic cart, and/or to purchase items, in addition to other suitable activities. In a number of embodiments, system 310 can host a voice-based e-commerce system (e.g., automated telephone ordering system, or ordering system using a voice assistant), or provide a server that interfaces with an audio communication application, on user device 320, which can allow user 330 to search for items (e.g., products), to inquire as to order status and/or other general questions (e.g., item information, store hours, promotions, etc.), to add items to an electronic cart, and/or to purchase items via speech, in addition to other suitable activities. In many embodiments, the voice assistant can run on user device 320.

In some embodiments, an internal network (e.g., 340) that is not open to the public can be used for communications between system 310 and user device 320 within system 300. In these or other embodiments, an operator and/or an administrator (e.g., an administrator 360) of system 310 can manage system 310, including NLU preprocessing subsystem 311, ASR subsystem 312, ML subsystem 313, request processing subsystem 314, entity rule subsystem 315, and/or admin module 316, the processor(s) of system 310, and/or the memory storage unit(s) of system 310 using the input device(s) and/or display device(s) of system 310 or via one or more admin devices (e.g., 350) coupled, through an internal network (not shown), to an administrator module (e.g., 316).

In certain embodiments, the user device (e.g., 320) can be desktop computers, laptop computers, a mobile device, and/or other endpoint devices used by one or more users (e.g., 330). In some embodiments, administrator devices (e.g., 350) can be desktop computers, laptop computers, a mobile device, and/or other endpoint devices used by one or more administrators (e.g., 360). A mobile device can refer to a portable electronic device (e.g., an electronic device easily conveyable by hand by a person of average size) with the capability to present audio and/or visual data (e.g., text, images, videos, music, etc.). For example, a mobile device can include at least one of a digital media player, a cellular telephone (e.g., a smartphone), a personal digital assistant, a handheld digital computer device (e.g., a tablet personal computer device), a laptop computer device (e.g., a notebook computer device, a netbook computer device), a wearable user computer device, or another portable computer device with the capability to present audio and/or visual data (e.g., images, videos, music, etc.). Thus, in many examples, a mobile device can include a volume and/or weight sufficiently small as to permit the mobile device to be easily conveyable by hand. For examples, in some embodiments, a mobile device can occupy a volume of less than or equal to approximately 1790 cubic centimeters, 2434 cubic centimeters, 2876 cubic centimeters, 4056 cubic centimeters, and/or 5752 cubic centimeters. Further, in these embodiments, a mobile device can weigh less than or equal to 15.6 Newtons, 17.8 Newtons, 22.3 Newtons, 31.2 Newtons, and/or 44.5 Newtons.

In many embodiments, system 310 can include one or more input devices (e.g., one or more keyboards, one or more keypads, one or more pointing devices such as a computer mouse or computer mice, one or more touchscreen displays, a microphone, etc.), and/or can comprise one or more display devices (e.g., one or more monitors, one or more touch screen displays, projectors, etc.). In these or other embodiments, one or more of the input device(s) can be similar or identical to keyboard 104 (FIG. 1 ) and/or a mouse 110 (FIG. 1 ). Further, one or more of the display device(s) can be similar or identical to monitor 106 (FIG. 1 ) and/or screen 108 (FIG. 1 ). The input device(s) and the display device(s) can be coupled to system 310 in a wired manner and/or a wireless manner, and the coupling can be direct and/or indirect, as well as locally and/or remotely. As an example of an indirect manner (which may or may not also be a remote manner), a keyboard-video-mouse (KVM) switch can be used to couple the input device(s) and the display device(s) to the processor(s) and/or the memory storage unit(s). In some embodiments, the KVM switch also can be part of system 310. In a similar manner, the processors and/or the non-transitory computer-readable media can be local and/or remote to each other.

Meanwhile, in many embodiments, system 310 also can be configured to communicate with one or more databases (e.g., a database 317, a new template database 3111, a new pattern database 3121, and an entity rule database 3151). The one or more databases can include a product database that contains information about products, items, or SKUs (stock keeping units), for example, including attribute names and attribute values, among other information, as described below in further detail. The one or more databases further can include one or more template rule database configured to store rules to rectify various system anomalies, as described below in further detail. The one or more databases can be stored on one or more memory storage units (e.g., a volatile memory or non-transitory computer readable media), which can be similar or identical to the one or more memory storage units (e.g., RAM or non-transitory computer readable media) described above with respect to computer system 100 (FIG. 1 ). Also, in some embodiments, for any particular database of the one or more databases, that particular database can be stored on a single memory storage unit or the contents of that particular database can be spread across multiple ones of the memory storage units storing the one or more databases, depending on the size of the particular database and/or the storage capacity of the memory storage units.

The one or more databases (e.g., 317, 3111, 3121, and 3151) can each include a structured (e.g., indexed) collection of data and can be managed by any suitable database management systems configured to define, create, query, organize, update, and manage database(s). Exemplary database management systems can include MySQL (Structured Query Language) Database, PostgreSQL Database, Microsoft SQL Server Database, Oracle Database, SAP (Systems, Applications, & Products) Database, and IBM DB2 Database.

Meanwhile, system 300, system 310, and/or the one or more databases (e.g., 317, 3121, 3131, and 3151) can be implemented using any suitable manner of wired and/or wireless communication. Accordingly, system 300 and/or system 310 can include any software and/or hardware components configured to implement the wired and/or wireless communication. Further, the wired and/or wireless communication can be implemented using any one or any combination of wired and/or wireless communication network topologies (e.g., ring, line, tree, bus, mesh, star, daisy chain, hybrid, etc.) and/or protocols (e.g., personal area network (PAN) protocol(s), local area network (LAN) protocol(s), wide area network (WAN) protocol(s), cellular network protocol(s), powerline network protocol(s), etc.). Exemplary PAN protocol(s) can include Bluetooth, Zigbee, Wireless Universal Serial Bus (USB), Z-Wave, etc.; exemplary LAN and/or WAN protocol(s) can include Institute of Electrical and Electronic Engineers (IEEE) 802.3 (also known as Ethernet), IEEE 802.11 (also known as WiFi), etc.; and exemplary wireless cellular network protocol(s) can include Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Evolution-Data Optimized (EV-DO), Enhanced Data Rates for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), Digital Enhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/Time Division Multiple Access (TDMA)), Integrated Digital Enhanced Network (iDEN), Evolved High-Speed Packet Access (HSPA+), Long-Term Evolution (LTE), WiMAX, etc. The specific communication software and/or hardware implemented can depend on the network topologies and/or protocols implemented, and vice versa. In many embodiments, exemplary communication hardware can include wired communication hardware including, for example, one or more data buses, such as, for example, universal serial bus(es), one or more networking cables, such as, for example, coaxial cable(s), optical fiber cable(s), and/or twisted pair cable(s), any other suitable data cable, etc. Further exemplary communication hardware can include wireless communication hardware including, for example, one or more radio transceivers, one or more infrared transceivers, etc. Additional exemplary communication hardware can include one or more networking components (e.g., modulator-demodulator components, gateway components, etc.).

In many embodiments, NLU preprocessing subsystem 311 can include a real-time anomaly rectification mechanism configured to: (a) identify a known issue(s) associated with a user request received from a user device (e.g., 320) of a user (e.g., 330), via a network (e.g., 340); (b) bypass the ordinary NLU processing path in system 310; and/or (c) interpret the user request and generate an output instruction, based at least in part on one or more new request templates associated with the user request from new template database 3111.

In a number of embodiments, ASR subsystem 312 can determine, in real-time after receiving the command data including audio data, the user request from the audio data. In many embodiments, ASR subsystem 312 can be implemented with hardware and/or software using one or more of statistically-based speech recognition algorithms, including hidden Markov models (HMI), dynamic time warping, neural networks, recurrent neural networks, deep feedforward neural network (DNN), connectionist temporal classification (CTC)-based end-to-end automatic speech recognition, or attention-based end-to-end automatic speech recognition, etc. In some embodiments, ASR subsystem 312 further can automatically correct known misclassification(s), potential or existing, in the user request, as determined by ASR subsystem 312, based on one or more entity rules in new pattern database 3121.

In some embodiments, ML subsystem 313 can interpret a user request in natural language and generate intent data and entity data from the user request accordingly. ML subsystem 313 can be implemented with hardware and/or software adopting one or more of NLU algorithms, such as Support Vector Machines (SVM), Bayesian Networks, Neural Networks, or Deep Learning, etc., and can constantly improve and automate the text interpretation process. In many embodiments, system 310 can generally use ML subsystem 313 for NLU processing and generating the intent data, the entity data, and/or the output instruction. In some embodiments, when system 310 and/or an operator/administrator (e.g., 360) of system 310 observes one or more misclassifications, potential or existing, in the outputs of ML subsystem 313, system 310 and/or administrator 360 can create one or more new request templates and allow NLU preprocessing subsystem 311 to take over NLU processing according to the new request template(s), as stated above.

In some embodiments, request processing subsystem 314 can perform the output instruction and transmit, to user device 320, a response to the user request. As an example, when the user request includes an audio inquiry, such as “When will the Black Friday sales start?,” the output instruction, as determined by ML subsystem 313 or NLU preprocessing subsystem 311, can comprise a command to play an audio message with a predetermined answer, and/or request processing subsystem 314 can comprise a server configured to stream the audio message to user 330, via user device 320 through network 340. In another example, the output instruction can include a request to process a payment authorization, and request processing subsystem 314 can host a transaction server configured to process the payment and return the result of the payment transaction.

In certain embodiments, entity rule subsystem 315 can analyze the entity data and generate entity information based on the entity data. In a number of embodiments, entity rule subsystem 315 also can determine that at least some entity information, as generated, can contain some known issue(s), and/or entity rule subsystem 315 can overwrite the entity information corresponding to one or more entity rules in entity rule database 3151.

In a number of embodiments, admin module 316 can receive and/or process commands from an administrator 360. In many embodiments, admin module 316 can provide a user interface to allow administrator 360 to observe the status, logs, inputs, and/or outputs, etc. of one or more of system 310, NLU preprocessing subsystem 311, ASR subsystem 312, ML subsystem 313, request processing subsystem 314, and/or entity rule subsystem 315. In many embodiments, admin module 316 also can provide a user interface to allow administrator 360 to manage, create, delete, or revise, via admin device 350 through wire or wireless connection (not shown), one or more data records in one or more databases, including database 317, new template database 3111, new pattern database 3121, and/or entity rule database 3151. For example, admin module 316 can provide a user interface for administrator 360 to create, delete, or edit one or more of new request templates in new template database 3111, new pattern templates in new pattern database 3121, or entity rules in entity rule database 3151.

In some embodiments, new template database 3111, new pattern database 3121, and/or entity rule database 3151 each can be an in-memory database and stored in the RAM (e.g. 208 (FIG. 2 )) or flash memory of at least one of: system 310, NLU preprocessing subsystem 311, ASR subsystem 312, or entity rule subsystem 315, etc. In certain embodiments, new template database 3111, new pattern database 3121, and/or entity rule database 3151 each can be stored in RAM and can be periodically persisted and/or backed up to one or more of non-transitory computer readable media, such as a hard drive (e.g., 114 (FIG. 1 )). In a number of embodiments, new template database 3111, new pattern database 3121, and/or entity rule database 3151 each can be stored in flash memory and can be loaded, in whole or in part, to the RAM in system 310, NLU preprocessing subsystem 311, ASR subsystem 312, and/or entity rule subsystem 315 for processing, at a suitable frequency, such as every 5 minutes, or 10 minutes, etc.

In a number of embodiments, new request templates in new template database 3111, new pattern templates in new pattern database 3121, and entity rules in entity rule database 3151 each can be deleted by administrator 360 via admin device 370 and admin module 314 or automatically by system 310 under certain conditions. For example, a condition can be when one or more of: ASR subsystem 312, ML subsystem 313, or entity rule subsystem 315 has/have learned the pattern(s) of new inputs and generated acceptable outputs.

Conventional systems are unable to at least automatically rectify in real-time anomalies in natural language processing (NLP) systems, other than to always wait until the machine learning module learns to recognize the new pattern or information and the correct response to such pattern/information, which can take hours if not days to happen, because conventional systems typically lack a by-pass mechanism to timely rectify the misclassification(s), potential or existing, and respond based on rules or templates. In many embodiments, real-time anomalies rectification modules provided by system 300, system 310, and/or NLU preprocessing subsystem 311 can advantageously address the problem by automatically determining whether ML subsystem 313 can likely misclassify a user request based on whether a corresponding rule/template exists, and can at least bypass ML subsystem 313 while using the corresponding rule/template in new template database 3111 to analyze the user request. Additionally, in many embodiments, the techniques provided herein are easy to implement, fast, and effective.

Turning ahead in the drawings, FIG. 4 illustrates a flow chart for a method 400 of automatically rectifying in real-time anomalies in NLP systems, according to an embodiment. Method 400 is merely exemplary and is not limited to the embodiments presented herein. Method 400 can be employed in many different embodiments or examples not specifically depicted or described herein. In some embodiments, the procedures, the processes, and/or the activities of method 400 can be performed in the order presented. In other embodiments, the procedures, the processes, and/or the activities of method 400 can be performed in any suitable order.

In these or other embodiments, one or more of the activities of method 400 can be implemented as one or more computing instructions configured to run at one or more processors and configured to be stored at one or more non-transitory computer readable media. Such non-transitory computer readable media can be part of system 310 (FIG. 3 ), NLU preprocessing subsystem 311 (FIG. 3 ), ASR subsystem 312 (FIG. 3 ), ML subsystem 313 (FIG. 3 ), request processing subsystem 314 (FIG. 3 ), and/or entity rule subsystem 315 (FIG. 3 ). The processor(s) can be similar or identical to the processor(s) described above with respect to computer system 100 (FIG. 1 ).

In some embodiments, method 400 and other blocks in method 400 can include using a distributed network including distributed memory architecture to perform the associated activity. This distributed architecture can reduce the impact on the network and system resources to reduce congestion in bottlenecks while still allowing data to be accessible from a central location.

Referring to FIG. 4 , method 400 can include a block 410 of receiving command data from a user device of a user. In a number of embodiments, the command data can correspond to a user request. Examples of user requests can include a specific query, such as a question regarding the price of an item or the items added to the electronic cart; a frequently asked question (FAQ) such as a question regarding delivery fees or weekly promotions; and/or an instruction, such as to add an item to the electronic cart or to check out.

Method 400 also can include a block 420 of retrieving, from a new template database (e.g., 3111 (FIG. 3 )), a new request template corresponding to the user request. In some embodiments, the new template database can comprise one or more new frequently-asked-questions (FAQ) templates or patterns and one or more corresponding new FAQ answers. In some embodiments, when the one or more new FAQ templates comprise the new request template and the one or more corresponding new FAQ answers, the one or more corresponding new FAQ answers can comprise the output instruction corresponding to the new request template.

For example, a new request template for a new FAQ can comprise one or more new FAQ templates, as the following exemplary regular expressions:

-   -   #45 What are Cyber Monday deals?     -   @template-Cyber_Monday_deals: ˜(?=.*?\bwhat|where\b) (?=.         *?\bcyber monday\b) (?=.*?\bdeal(s)\b).*s     -   @template-Cyber_Monday_deals: ˜(?=.*?\bshowb) (?=.*?\bcyber         monday\b) (?=.*?\bdeal(s)\b).*s         For the same example, the new template database also can         comprise one or more new FAQ answers corresponding to the new         request template for “What are Cyber Monday deals?”, as the         following exemplary regular expression:     -   what_are_Cyber_Monday_deals?=Visit walmart.com for details on         Cyber Monday. Deals officially start the Monday following         Thanksgiving, on December 2^(nd).

In some embodiments, a new request template can comprise one or more new patterns without any corresponding answers in the new template database, or vice versa.

In a number of embodiments, the new template database (e.g., 3111 (FIG. 3 )) accessed in block 420 can be an in-memory database and/or can be stored in a memory data store, such as a RAM or a flash memory. In some embodiments, block 420 can be configured to periodically, at a frequency, load or refresh a portion of or the entire new template database to be processed in one or more of the blocks 410-460 of method 400. In several embodiments, the frequency can be at least as great as a predetermined frequency threshold, such as every 3 minutes, 5 minutes, or 15 minutes, etc.

Method 400 further can include a block 430 of determining whether the new request template corresponding to the user request exists in the new template database (e.g., 3111 (FIG. 3 )).

Method 400 also can include a block 440 of retrieving, from the new template database (e.g., 3111 (FIG. 3 )), an output instruction corresponding to the new request template, when the new request template is found. In some embodiments, block 440 further can include extracting, using NLU processing, intent data and entity data from the user request and merging the intent data and/or entity data into the output instruction. The NLU processing in block 420 can be performed by system 300 (FIG. 3 ), system 310 (FIG. 3 ), and/or NLU preprocessing subsystem 311 (FIG. 3 ).

Method 400 additionally can include a block 450 of determining, by a machine learning system, the output instruction corresponding to the user request, when the new request template is not found. The machine learning system can be similar or identical to system 300 (FIG. 3 ), system 310 (FIG. 3 ), and/or ML subsystem 313 (FIG. 3 ).

Moreover, method 400 can include a block 460 of transmitting the output instruction to a request processing system to perform the output instruction and transmit, to the user device, a response to the user request.

Turning ahead in the drawings, FIG. 5 illustrates a flow chart for a method 500 of automatically recognizing speeches including a real-time anomalies rectification mechanism, according to the embodiment of FIG. 4 . Method 500 is merely exemplary and is not limited to the embodiments presented herein. Method 500 can be employed in many different embodiments or examples not specifically depicted or described herein. In some embodiments, the procedures, the processes, and/or the activities of method 500 can be performed in the order presented. In other embodiments, the procedures, the processes, and/or the activities of method 500 can be performed in any suitable order. In still other embodiments, one or more of the procedures, the processes, and/or the activities of method 500 can be combined or skipped. In some embodiments, system 300 (FIG. 3 ), system 310 (FIG. 3 ), and/or ASR subsystem 312 (FIG. 3 ) can be suitable to perform method 500 and/or one or more of the activities of method 500. In many embodiments, method 500 can be performed after block 410 (FIG. 4 ).

Referring to FIG. 5 , method 500 can include a block 510 of determining, in real-time after receiving the command data, using automated speech recognition (ASR) processing, the user request from audio data of the command data. In some embodiments, the command data can comprise utterances by a user (e.g., 330 (FIG. 3 )) transmitted via a telephone or a voice-based computer application (App), such as a voice assistant. In some embodiments, the ASR processing in block 510 can be performed by a machine learning module trained to recognize speeches or utterances by users.

Method 500 further can include a block 520 of retrieving, from a new pattern database (e.g., 3121 (FIG. 3 )), in real-time after determining the user request from the audio data, a new pattern template corresponding to the user request. In some embodiments, the ASR processing in block 510 can be known to often misclassify some words that sound similar, such as “car,” “cart,” and “card.” As such, in a number of embodiments, block 520 can confirm whether a misclassification in at least a part of the user request is known or likely, and whether a solution can be provided in the new pattern database by searching for a new pattern template corresponding to the user request from the new pattern database.

In many embodiments, the new pattern database (e.g., 3121 (FIG. 3 )) can be an in-memory database stored in RAM or flash memory. In some embodiments, block 520 additionally can include loading or refreshing at least a portion of the new pattern database at a frequency at least as great as a predetermined threshold, such as every 5 minutes, 7 minutes, or 10 minutes.

Method 500 also can include 530 of revising the user request based on the new pattern template, when the new pattern template is found in the new pattern database (e.g., 3121 (FIG. 3 ). As an example, when a portion of the user request originally recognized as “make it to” can be corrected to be “make it two,” the new pattern template can be represented by a regular expression as below:

-   -   @template-make_it_two; (?<prefix>(.*?))( )? \bmake\b         (?<body>(.*?)) to(o)?

The corresponding answer/correction can be:

make_it_two=<prefix>\make\<body>\two

Turning ahead in the drawings, FIG. 6 illustrates a flow chart for a method 600 of automatically interpreting entity data including a real-time anomalies rectification mechanism, according to another embodiment. Method 600 is merely exemplary and is not limited to the embodiments presented herein. Method 600 can be employed in many different embodiments or examples not specifically depicted or described herein. In some embodiments, the procedures, the processes, and/or the activities of method 600 can be performed in the order presented. In other embodiments, the procedures, the processes, and/or the activities of method 600 can be performed in any suitable order. In still other embodiments, one or more of the procedures, the processes, and/or the activities of method 600 can be combined or skipped. In some embodiments, system 300 (FIG. 3 ), system 310 (FIG. 3 ), and/or ASR subsystem 312 (FIG. 3 ) can be suitable to perform method 600 and/or one or more of the activities of method 600. In some embodiments, system 300 (FIG. 3 ), system 310 (FIG. 3 ), and/or entity rule subsystem 315 (FIG. 3 ) can be suitable to perform method 600 and/or one or more of the activities of method 600. In many embodiments, method 600 can be performed before block 460 (FIG. 4 ).

Referring to FIG. 6 , method 600 can include a block 610 of extracting, prior to transmitting the output instruction to the user device, entity information from the entity data. Exemplary entity data can include one or more of a unit (e.g., “pound”, “inch(es),” or “feet”), a brand, an item (e.g., product), an item type, a quantity, and so forth.

In many embodiments, the entity rule database can be an in-memory database stored at the RAM, flash memory, or other volatile/nonvolatile memory, etc. and can be loaded to or refreshed at a main memory where method 600 is executed every 3 minutes, 5 minutes, 12 minutes, etc.

Method 600 also can include a block 620 of retrieving, from an entity rule database (e.g., 3151 (FIG. 3 )), one or more entity rules corresponding to the entity data.

Method 600 also can include a block 630 of overwriting the entity information corresponding to the one or more entity rules, when the one or more entity rules are found.

For instance, when a user request, “add X Y Z,” includes a new item “X Y Z,” block 610 that can be implemented by a module, subsystem, or system, such as NLU subsystem 311 (FIG. 3 ) or ML subsystem 313 (FIG. 3 ), can extract from the entity data, “X Y Z,” the entity information as: {“quantity”: [“X”], “unit”: [“Y”], “item”: [“Z”]}.

If an operator or an administrator (e.g., 360 (FIG. 3 )) or a system (e.g., system 300 or system 310) knows that the new item will launch soon (e.g., when a record for the new item is added to an item database but before an ML module for ASR can be trained) or observes that this new entity has been searched for or requested by users (e.g., 330 (FIG. 3 )) but block 610 has been incorrect classify the entity “X Y Z”, a new entity rule as below can be added to the entity rule database:

-   -   {template-add: (?<product>XYZ)}

As soon as the new entity rule is added (or after loading the entity rule database, as updated), block 620 can determine that “X Y Z” is a new entity, and block 630 can then overwrite the entity information identified by block 610.

In many embodiments, the techniques described herein can provide a practical application and several technological improvements. In some embodiments, the techniques described herein can provide for automatically rectifying in real-time anomalies in natural language processing systems. Additionally, the techniques described herein can be easy to implement yet effective.
